//! # Daemon Interface
//!
//! Background process that owns agent state and communicates with TUI
//! clients over a Unix-socket IPC protocol.
//!
//! ## Architecture
//!
//! ```text
//! src/
//! ├── lib.rs        — Crate root, module declarations, re-exports
//! ├── server.rs     — Daemon server: session creation, socket bind, client loop
//! ├── client.rs     — IPC client for attaching to daemon (moved from attach mode)
//! ├── key_code.rs   — KeyCode <-> KeyAction conversions
//! ├── state.rs      — AppStateRest, DaemonState, supporting types, create_session
//! └── handler.rs    — Action, apply_action, handle_key, IPC request handler
//! ```
//!
//! ## Modes
//!
//! - **Server** (`run_daemon`): creates a session, binds a Unix socket, accepts
//!   incoming clients, and processes their IPC `ClientRequest`s.
//! - **Client** (`run_attach`): connects to a running daemon over its Unix socket,
//!   enters raw TUI mode, forwards keystrokes, and renders state updates.
